Cannot Send Messages in FB Messenger with this Enabled. FB Messenger also does not change, but regular FB Pages do. Need to be able to send Messages.

Now I cannot get back into FB

Nem igazán akar működni.Csak ideiglenesen,alkalmanként.

Matt, would there by any way to not use the "upload.facebook" URL? It is causing me trouble with sending links, I always have to edit them. Thanks!

Perfect. Worked Brilliantly

As of 10/21/20 no longer working on Firefox despite reloading it. It's unfortunate because it was very helpful while it lasted. At least it's still working on Chrome.

Very nice. Thank you. It works again with firefox 82 and facebook.
